Dark Energy Constraints from Needlets Analysis of Wmap3 and NVSS Data
Davide Pietrobon, Amedeo Balbi, Domenico Marinucci
We cross-correlate the new 3 year Wilkinson Microwave Anistropy Probe (WMAP3) cosmic microwave background (CMB) data with the NRAO VLA Sky Survey (NVSS) radio galaxy data, and find…
Polynomial Cointegration among Stationary Processes with Long Memory
Marco Avarucci, Domenico Marinucci
n this paper we consider polynomial cointegrating relationships among stationary processes with long range dependence. We express the regression functions in terms of Hermite polyn…
High-frequency asymptotics for subordinated isotropic fields on an Abelian compact group
Domenico Marinucci, Giovanni Peccati
Let T* be a random field indexed by an Abelian compact group G, and suppose that T* has the form T* = F(T(g)), where T is Gaussian and isotropic. The aim of this paper is to establ…
Some characterizations of the spherical harmonics coefficients for isotropic random fields
P. Baldi, D. Marinucci
In this paper we provide some simple characterizations for the spherical harmonics coefficients of an isotropic random field on the sphere. The main result is a characterization of…
High Frequency Asymptotics for Wavelet-Based Tests for Gaussianity and Isotropy on the Torus
Paolo Baldi, Gérard Kerkyacharian, Domenico Marinucci +1
We prove a CLT for skewness and kurtosis of the wavelets coefficients of a stationary field on the torus. The results are in the framework of the fixed-domain asymptotics, i.e. we…
Asymptotics for spherical needlets
P. Baldi, G. Kerkyacharian, D. Marinucci +1
We investigate invariant random fields on the sphere using a new type of spherical wavelets, called needlets. These are compactly supported in frequency and enjoy excellent localiz…
